Question

If 12 years are added to 2/3 age of Rani , she will be three years older than today. What is Rani's present age

Answer 1

Lets assume Rani's present age as x. So, 2/3 of x+ 12= x+3. If we solve this equation we get x= 27. So, Rani's present age is 27.

Answer 2

Let Rani's present age is x.
If 12 years added to 2/3 age of Rani, she will be 3 years older than today.
Now, 2/3 of x+12=x+3
2/3 of x=x+3-12
2/3 of x=x-9
x=3/2×(x-9)
x=(3x-27)/2
2x=3x-27
x=27 yrs
So, Rani is 27 years old.
